Zibby Thorne doesn't know what possessed her to buy an antique dollhouse--she doesn't even like dolls. But when her friends and family start having bizarre accidents clearly connected to the dollhouse, she can't ignore the menacing structure any longer. Zibby is sure that one particularly creepy doll in a gray dress is somehow responsible for the trouble. She discovers the doll is controlled by the spirit of sweet Miss Honeywell, a vengeful governess who seeks to control Zibby and her friends from beyond the grave. They must find a way to stop Miss Honeywell before her wrath becomes deadly.
